Patay
Long before sugar reached the dry northwest, the pods of the algarrobo tree were the region's sweetness, and patay is the oldest way of keeping them: the pods are ground, the flour is moistened and pressed into a cake that dries into something dense, fudgy and naturally sweet, with notes of cocoa, coffee and caramel. In Santiago del Estero you still buy it in round slabs at markets and roadside stalls, to eat with mate or to crumble into milk. Harina de algarroba comes from the South American Prosopis tree; look for it in health-food shops or online, and mesquite flour is the same family and works well. Mediterranean carob flour is different and tastes more bitter. Too much water is the way most first attempts go wrong: the cake should be pressed from a damp, crumbly mix, not a batter, or it bakes up gummy. Chef's tip: sieve the flour twice; algarroba flour clumps, and lumps stay as hard grains.
